You had so many things that aligned to make that show a world beater like Hendo and Bisping's season on TUF, like GSP (who got a bigger pop than Brock in Vegas) against a dangerous Thiago Alves and the whole 'milestone event thing.'

That being said there's nothing to say that, with a similar push, they couldn't have beaten that.

The 24/7 style pre programming would have been a huge campaign for Fedor and if they'd have stuck maybe Anderson or GSP on the card as well and stacked on a few grudge matches/TUF coaching rivalries they'd have boosted their revenue by a massive ammount.

Fedor could have easily armbarred himself to one of the biggest single pay days in UFC history.

Winston you need to get off the Lesnar band wagon, Lesnar wasn't the reason UFC 100 did 1.6 million buys, he played a part because he was squaring off with Mir again however it may have had something to do with the WW title fight with the greatest WW ever against one of the best WW's in the world, arguable the greatest pound for pound fighter ever Dan Henderson in a seriously hyped grudge match against Michael Bisping.

Which ever way you look at it, you can list a whole number of fighters against Fedor and say it would have been the biggest fight in history money wise.
